The Faraya-Chabrouh Dam is a dam above the village of Faraya Lebanon, 40 kilometers northeast of Beirut that was inaugurated in 2007. The dam has a height of 63 metres. The reservoir has a capacity of some 8 million cubic meters and is some 1300 metres in length. The dam is located in rural Lebanon and is surrounded by farmland. Agricultural lands stretch far below the Faraya-Chabrouh Dam and the water is used from the reservoir to irrigate the lands, providing an essential resource to thousands of people in the villages below. Chabrouh dam is located on Wadi Chabrouh river in Faraya, about 40 km north-east of Beirut. This project will provide potable water during the summer for Kesrouan region (around 250,000 inhabitants). The dam is a bituminous face rockfill dam (BFRD), with maximum height of 65m, crest length of 470m at 1618m above sea level and a volume of rockfill of 1,500,000 m3. The upstream and downstream slopes are 1V:1.7H. The upstream bituminous slab has a total area of 37,000 m2 and total thickness of 22 cm (2 layers of 6 cm and a base of 10 cm). The embankment is divided into eight zones of materials as well as filters and drains. The rockfill for the embankment is selected from two quarries at about 5 km from the dam site. Zone I (1800–1860) is a mixture of hard limestone (above 1840) and chalky limestone (Average Los Angeles 50) used for embankment material 3B and 3BE (see figure 2.2). Zone II is a formation of very hard limestone (Average Los Angeles 25) used for concrete aggregates and materials 2A, 2B, 3A, 4 and draining systems (see figure 2.3). The test layers performed with fill material 3B, showed that after compaction, the percentage of fines was greater than expected with Kh/Kv =100. These results led to the implementation of a draining chimney located at 45 m from the upstream face of the embankment, aiming at controlling all potential leakages, and channelling the water towards the horizontal drains of the embankment. The construction of the dam was done in phases taking into consideration the fact that the site was covered with snow during at least 4 months of the year. The deviation of the water course was delayed in order to finish the deviation tunnel. Meanwhile, the works were taking place on the left and right banks separately ==Description== The project consists of the construction of the three following elements: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chabrouh Dam」の詳細全文を読む スポンサード リンク
